Research Interests

As human activities are fundamentally altering the environment, our ability to solve many environmental and societal problems over the next several decades will depend on our understanding of the basic structure and function of ecosystems and how they respond to current and future environmental changes. A disproportionate amount those functions and responses occur or are mediated in soil. In general, my research questions address how plants and soil organisms interact with their environment to control the cycling of carbon and nutrients via decomposition of organic matter, and how those processes are altered by global environmental changes.

 

For example, acid rain and associated nitrogen depositon – pollution derived from burning fossil fuel – can alter the function of both plants and soil microorganisms. This is particularly relevant in the Great Lakes region and Northeast Ohio where acid rain and land use change has increased acidity and the bioavailability of nitrogen in soils, surface waters, and ground waters.

 

Below are a sample of on-going projects. In my lab, we take a collaborative approach to science, and we employ a variety of methods and techniques ranging from stable isotopic techniques to microbial community characterization. 

Some Current Projects

  • Biogeography and spatial structure of ecological communities in relation to ecosystem properties (more). 

  • Soil acidification and its effects on carbon and nutrient cycling and productivity in hardwood forests (more).

  • Fungal diversity and ecosystem function in beech-maple forests (more).

  • Winter soil ecology and altered precipitaton dynamics (more).

  • Controls on the production and emission of greenhouses gases (methane, carbon dioxide, and nitrous oxide) from forest, wetland, and agricultural soils (more).
